Blazing temperatures ahead for Los Angeles and inland valleys
Southern California is about to be scorched by an intense heat wave this week, with the most extreme temperatures forecast for Wednesday and Thursday. Inland areas, especially in Los Angeles County, will face the brunt of this early summer heat surge, while coastal cities will also experience unusually high readings.
According to Ryan Kittell, a National Weather Service meteorologist in Oxnard, this week’s pattern marks a “noticeable warm-up” with temperatures ranging from 90°F to 100°F (32°C to 38°C) away from the coast. Some valleys might even approach record-breaking highs.
Where the heat will hit hardest
The San Fernando, San Gabriel, and Santa Clarita valleys are set to sizzle. Forecasts show that Woodland Hills and Canoga Park could top 100°F (38°C), traditionally the hottest locations in Los Angeles County.
Moving farther inland, Palm Springs is expected to peak at a scorching 105°F (41°C) by Thursday, underlining the extreme heat risk for the desert regions.
Even areas that usually benefit from the Pacific Ocean’s moderating breeze will warm up significantly. Los Angeles International Airport may tie its May 21 record at 78°F (26°C), while Long Beach Airport could hit 87°F (31°C). Santa Barbara might reach its previous record of 79°F (26°C).
Serious inland risks and past rescues
The most dangerous conditions will be inland, where temperatures and dry air combine to increase the risk of heat-related illnesses. The weather service is urging residents to avoid strenuous outdoor activity between 10 a.m. and 6 p.m., especially in valley and desert zones.
Earlier this month, emergency crews had to respond to several heat-related incidents, including:
- 15 people rescued in Orange County and 9 in Riverside County on May 10, when temperatures soared into the high 90s (mid-30s°C).
- A hiker in the Hollywood Hills was airlifted due to heat exhaustion.
Fire weather outlook and air quality
While the heat and localized gusty winds raise concerns, no red flag warnings have been issued yet. Vegetation remains relatively green following the recent rainy season, which helps curb fire danger. However, dry grass patches still pose a wildfire risk, especially during peak heat.
When relief is expected
This intense high-pressure system is projected to weaken by Friday, ushering in cooler ocean air. By the weekend, much of Los Angeles County should enjoy more moderate temperatures, in the 70s to low 80s (21°C to 28°C), just in time for Memorial Day.
While the deserts will remain hot through Saturday and Sunday, most of Southern California can look forward to milder weather ahead.
